range_trim

["Andreas J. Guelzow" <aguelzow math concordia ab ca>]

Hi

perhaps I am missing the point, but is range_trim intentionally written 
to be slow? sheet_is_region_empty checks essentially every cell in 
range. Therefore if the range has many rows to trim it checks most 
cells, if there are no rows to trim it checks the cells in the last row 
about log n times. Wouldn't it be usually be faster simply to start at 
the bottom and check whether the row is empty and trim it if possible?
